6JSC/ALA/31/rev/Sec final 12 March 2015 page 1 of 18 To: Joint Steering Committee for Development of RDA From: Judith A. Kuhagen, Secretary, JSC Subject: Subject Relationship Element in RDA Chapter 23 The text below reflects the decisions made by the Joint Steering Committee during its November 2014 meeting and via email after the meeting. Additions to represent other subject relationships (e.g., for persons, families, and corporate bodies that are the subject of a work) will be added in a later release. ===== 0.2 Conceptual Models Underlying RDA 0.2.1 General A key element in the design of RDA is its alignment with the conceptual models for bibliographic and authority data developed by the International Federation of Library Associations and Institutions (IFLA): Functional Requirements for Bibliographic Records (FRBR)4 Functional Requirements for Authority Data (FRAD)5 Functional Requirements for Subject Authority Data (FRSAD).6 The FRBR, FRAD, and FRSAD models provide RDA with an underlying framework that has the scope needed to support: a) comprehensive coverage of all types of content and media b) the flexibility and extensibility needed to accommodate newly emerging resource characteristics c) the adaptability needed for the data produced to function within a wide range of technological environments d) coverage of all types of subjects. ----------------------------------------------------------------------------------------------------------4 IFLA Study Group on the Functional Requirements for Bibliographic Records, Functional Requirements for Bibliographic Records: Final Report (München: K.G.

In future releases, the scope of RDA may be extended to cover additional attributes and relationships that are associated with these four entities and support resource discovery, but are not currently defined in FRBR. Attributes and relationships currently out of scope. Attributes and relationships associated with these four entities whose primary function is to support user tasks related to resource management (e.g., acquisition, preservation) are currently out of scope. -----------------------------------------------------------------------------------------------------------7 See the attributes defined in sections 4.2–4.5 and the relationships defined in sections 5.2–5.3 of FRBR. For details on the correspondence between RDA elements and FRBR attributes and relationships, see RDA to FRBR Mapping, http://www.rda-jsc.org/docs/5rdardafrbrmappingrev2.pdf. 0.2.3 Alignment with FRAD [instruction at 0.3.3 renumbered as 0.2.3 and footnote renumbered] The RDA data elements for describing entities associated with a resource generally reflect the attributes and relationships associated with the entities person, family, corporate body, and place, as defined in FRAD.8 Those entities are defined in RDA as follows: person—an individual or an identity established by an individual (either alone or in collaboration with one or more other individuals) family—two or more persons related by birth, marriage, adoption, civil union, or similar legal status, or who otherwise present themselves as a family corporate body—an organization or group of persons and/or organizations that is identified by a particular name and that acts, or may act, as a unit place—a location identified by a name. 6JSC/ALA/31/rev/Sec final 12 March 2015 page 3 of 18 RDA also covers additional attributes of the entity work that are defined in FRAD but are not included in FRBR. Attributes associated with the entities name, identifier, controlled access point, and rules, as defined in FRAD, are covered selectively. In future releases, the scope of RDA may be extended to cover additional attributes and relationships (associated with the entities person, family, corporate body, place, work, expression, name, identifier, controlled access point, and rules) that support resource discovery, but are not currently defined in FRAD. Attributes and relationships currently out of scope. The following attributes and relationships are currently out of scope: attributes and relationships associated with the entities concept, object, and event, as defined in FRAD relationships between controlled access points, as defined in FRAD attributes and relationships (associated with the entities person, family, corporate body, work, and expression) whose primary function is to support user tasks related to rights management. ----------------------------------------------------------------------------------------------------------8 See the attributes defined in sections 4.1–4.7 and the relationships defined in sections 5.3–5.4 of FRAD. For details on the correspondence between RDA elements and FRAD attributes and relationships, see RDA to FRAD Mapping, http://www.rda-jsc.org/docs/5rdardafradmappingrev.pdf. 0.2.4 Alignment with FRSAD The RDA element for the subject relationship generally reflects the relationship associated with the entity work as defined in FRSAD.9 -----------------------------------------------------------------------------------------------------------9 See the relationship defined in section 5.1 of FRSAD. 0.3 Relationship to Other Standards for Resource Description and Access 0.3.1 General RDA is built on foundations established by the Anglo-American Cataloguing Rules (AACR) and the cataloguing traditions on which it was based.10 11 12 13 Instructions derived from AACR have been reworked to produce a standard that will be easier to use, more adaptable, and more cost-efficient in its application. A key factor in the design of RDA has been the need to integrate 6JSC/ALA/31/rev/Sec final 12 March 2015 page 4 of 18 data produced using RDA into existing databases developed using AACR and related standards. Other key standards used in developing RDA include the International Standard Bibliographic Description (ISBD),14 the MARC 21 Format for Bibliographic Data,15 and the MARC 21 Format for Authority Data.16 The metadata standards used in other communities (archives, museums, publishers, semantic web, etc.) were taken into consideration in the design of RDA. The goal was to attain an effective level of interoperability between those standards and RDA. ----------------------------------------------------------------------------------------------------------10 Charles A.

Supplementary guidelines and instructions are provided in appendices as follows:22 ... Appendix M lists terms used as designators to indicate the nature of a relationship between a work and its subject. The relationship designators define the relationship more specifically than the relationship element by itself. The appendix provides definitions for terms used as relationship designators and instructions on their use. ---------------------------------------------------------------------------------------------------20 Development of the placeholder Sections and chapters covering the attributes of concept, object, and event defined in FRAD is dependent on the outcomes from consolidation of the FR models. 21 Chapters marked with an asterisk may be developed in a future release of RDA. 22 Appendices marked with an asterisk may be developed in a future release of RDA. ===== 0.6.1 General [for changes to 0.6.1, see 6JSC/BL/15/rev/Sec final] ===== 0.6.2 Core Elements [for changes to 0.6.2, see 6JSC/BL/15/rev/Sec final] ===== 0.6.10 Section 7: Recording Subject Relationships When recording relationships between a work and its subject, include as a minimum at least one subject relationship element that is applicable and readily ascertainable. ===== 6JSC/ALA/31/rev/Sec final 12 March 2015 page 7 of 18 0.7 Access Points [instruction unchanged except for the addition of the third line in the list after the 2nd paragraph as shown below] primary relationship between a manifestation and a work or expression embodied in the manifestation relationships between a resource and persons, families, and corporate bodies associated with that resource relationships between a work and its subject relationships between works, expressions, manifestations, and items relationships between persons, families, and corporate bodies. ===== 0.10 Examples [instruction unchanged except for the 7th paragraph below] When using an authorized access point or structured description to record a relationship to a related work, expression, manifestation, or item, the examples illustrate the use of relationship designators. The authorized access point or structured description is preceded by an introductory phrase paralleling the applicable relationship designator (see appendix J and appendix M). ===== Section 7: Recording Subject Relationships 23 GENERAL GUIDELINES ON RECORDING RELATIONSHIPS BETWEEN WORKS AND SUBJECTS 23.0 Scope This chapter provides general guidelines and instructions on recording relationships between works and subjects. It includes: a) an explanation of key terms (see 23.1) b) the functional objectives and principles underlying the general guidelines and instructions in chapter 23 (see 23.2) c) the core elements for recording subject relationships to entities (see 23.3) d) the use of identifiers, authorized access points, and/or descriptions to record subject relationships (see 23.4) 6JSC/ALA/31/rev/Sec final 12 March 2015 page 8 of 18 e) the use of relationship designators to indicate the specific subject relationship between works and entities (see 23.5). 23.1 Terminology 23.1.1 Explanation of Key Terms There are a number of terms used in this chapter that have meanings specific to their use in RDA. Some of these terms are explained at 23.1.2–23.1.6. All terms with a specific technical meaning are defined in the glossary. 23.1.2 Work The term work▼ refers to a distinct intellectual or artistic creation (i.e., the intellectual or artistic content). The term work can refer to an individual work, an aggregate work, or a component of a work. 23.1.3 Subject The term subject▼ refers to a term, phrase, classification number, etc., that indicates what the work is about. 23.1.4 Access Point The terms access point and authorized access point are used as follows: The term access point▼ refers to a name, term, code, etc., representing a specific entity (work, expression, person, family, corporate body, or other entity that serves as the subject of a work). The term authorized access point▼ refers to the standardized access point representing an entity. The authorized access point representing a work or expression is constructed by combining (in this order): a) the authorized access point representing a person, family, or corporate body responsible for the work, if appropriate b) the preferred title for the work c) other elements as instructed at 6.27-6.31. The authorized access point representing a person, family, or corporate body is constructed using the preferred name for person, family, or corporate body. The authorized access point representing the subject of a work may be a controlled subject term or combination of terms, or a classification number, as specified in an identifiable subject system. 6JSC/ALA/31/rev/Sec final 12 March 2015 page 9 of 18 23.1.5 Identifiable Subject System The term identifiable subject system▼ refers to a standard for subject access points and/or classification numbers used by the agency creating the data. It may be used in determining the names or terms, other identifying attributes, and relationships representing the subject of a work. It may also include rules for application of terms, systematic combination of terminology (e.g., pre-or post-coordination), and guidelines on cardinality and depth of assignment. 23.1.6 Relationship Designator The term relationship designator▼ refers to a designator that indicates the nature of the relationship between a work and its subject. A relationship designator is recorded with the authorized access point, identifier, and/or description representing the subject of the work. 23.2 Functional Objectives and Principles The data recorded to reflect the subject relationship should enable the user to find all works about a particular subject. To ensure that the data created using RDA meet that functional objective, the data should reflect all significant subject relationships. 23.3 Core Elements When recording relationships between a work and its subject, include as a minimum at least one subject relationship element that is applicable and readily ascertainable. 23.4 Subject Relationship CORE ELEMENT 23.4.1 Basic Instructions on Recording Subject Relationships 23.4.1.1 Scope Subject relationship▼ refers to the relationship between a work and an identifier, an authorized access point, and/or a description that indicates what the work is about. 23.4.1.2 Recording the Related Subject Record the related subject of the work by using one or more of these techniques: a) identifier (see 23.4.1.2.1) b) authorized access point (see 23.4.1.2.2) 6JSC/ALA/31/rev/Sec final 12 March 2015 page 10 of 18 and/or c) description of the related subject (see 23.4.1.2.3). Record an appropriate relationship designator to specify the nature of the relationship (see 23.5). 23.4.1.2.1 Identifier for the Subject Provide an identifier for the subject. EXAMPLE Library and Archives Canada control number: 0200B4753 Identifier for Icelandic Canadians, the subject of the work Selected resource material on Canadians of Icelandic descent German National Library: http://d-nb.info/gnd/119545373 Identifier for Angela Merkel, the subject of the work Frauen, Politik und Medien Medical Subject Headings control number: D011187 Identifier for Posture, the subject of the work Clinical disorders of balance, posture and gait Integrated Taxonomic Information System serial number: 180693 Identifier for Cervidae, the subject of the work Szarvasok nyomában és egyéb írások Library of Congress control number: n 78096930 Identifier for Harvard University, the subject of the work The Harvard monthly 23.4.1.2.2 Authorized Access Point Representing the Related Subject Provide an authorized access point representing the related subject. The access point may be a controlled subject term or a combination of terms, or a classification number, as specified in an identifiable subject system. EXAMPLE Aquatic animals Authorized access point in the Sears list of subject headings for the subject of the work Ugly creatures under water GV1796.F55 Authorized access point in the Library of Congress Classification system for the subject of the work Guía del flamenco 6JSC/ALA/31/rev/Sec final 12 March 2015 page 11 of 18 Canada. Constitution Act, 1982 Authorized access point for the subject of the work The aboriginal rights provisions in the Constitution Act, 1982 Literacy Bilingualism Authorized access points in the Education Resources Information Center thesaurus for the subjects of the work Literacy in the early years and English as an additional language Chanel, Coco, 1883–1971 Authorized access point for the subject of the work Mémoires de Coco 349.73 Authorized access point in the Dewey Decimal Classification system for the subject of the work An introduction to the American legal system Bianchi (Firm) Autobianchi (Firm) Authorized access points for the subjects of the work Dalle auto Bianchi alle Autobianchi 23.4.1.2.3 Description of the Subject of the Work Provide a description of the related subject by using either a structured description or an unstructured description (e.g., keywords), as appropriate. EXAMPLE A biography of Martin Luther King, Jr., covering his childhood, leadership, powerful speeches, assassination, and greatest influences Description of the subject of the work Free at last! knitting; patterns; sweaters; Fair Isle Description of the subject of the work Meg Swansen’s knitting This documentary explores the history of electric automobiles in the United States, focusing specifically on the General Motors EV1.

A relationship designator is recorded with the identifier, authorized access point, and/or description representing the subject of the work. The defined scope of a relationship element provides a general indication of the relationship between a work and its subject. Relationship designators provide more specific information about the nature of the relationship (e.g., commentary in, evaluation of). 23.5.1.2 Sources of Information Take information on the nature of the subject relationship from any source. 23.5.1.3 Recording Relationship Designators Record one or more appropriate terms from the list in appendix M to indicate the specific nature of the subject relationship. EXAMPLE commentary on Resource described: Tingey, Robert J. Commentary on Schematic geological map of Antarctica, scale 1:10,000,000. Relationship designator recorded in conjunction with an identifier for Schematic geological map of Antarctica critiqued in Resource described: Euryanthe / Carl Maria von Weber. Relationship designator recorded in conjunction with the authorized access point for Euryanthe and Carl Maria von Weber’s dramaturgy of German opera If none of the terms listed in appendix M is appropriate or sufficiently specific, use another concise term to indicate the nature of the relationship. ===== 25.1.1.3 Recording Relationships to Related Works [instruction unchanged except for examples as explained below] 6JSC/ALA/31/rev/Sec final 12 March 2015 page 13 of 18 [1st example box: examples unchanged except for deletion of 2nd example (“Reviewed in: ...”) and revision of former 3rd example] Finding aid: http://bibpurl.oclc.org/web/14192 Resource described: Emery E.
